` 'smsen specification.

IThis invention relates to improvement in signal devices and lmereespecially?te amig4 tral- 1tit-wise especiallyL adaptedctdr ar vehicle, subir as i a motor ='vehicle, for 'indicating to following drivers they turnsiand fstopsin'- tachr'nent to aw'ehicle, `andis sodesign tended to -be made bythe vehiclef'carrying the device. y improved signal-'ldeviceiis smpiefin construction andcariihe easil-ylaud cheaply made. It is adapted for ready'ated that `it may be both automatically and finanuallys-operated. 'It' is also soJ constructed thatcit may carrysuch tags -or-emblemslas may bendes-ned. For example, 'fthe'vehicle license tag may beiattached to the fdevice.

\0therf features and advantages of-:rnyldevice will appear more fully' as I f proceed with my specification.

As shown in the drawings, v10 indicatesthei Hoor-board of af nrot'or velie'le. 11 indicates the steering column. The signal device indicated in general by A is attached at the rear of the vehicle to the mudguard, body, or other suitable support, in any desired manner such as by means of a bracket 12.

The signal device comprises in general a fiat circular housing or casing 20, formed in any suitable manner such as by means of a back plate 2l and front plate 22, having telescoping flanges 21 and 22 respectively. The back plate 21 is provided at the top with a circular opening 23 having a diameter substantially equal to one half ofthe diameter of the plate itself. Directly opposite this opening 23, the forward plate 22 is provided with a similar registering opening 24,

=Tfhe fdisk29 is rotatedby'means of the two cables 40; and ELi1 respectively which are Wrapped pathwayaroundy lthe Ygrooves# on the* 'pulley ao and fastened at'r their 1 ends. These t-'Wo eabflesl'lland 41 afreled forwardlyi anch attached to two spiral springs y 40 ende/i1 which in: turnf area fasteiiegdf to" two c armsfiaed 46,1 attached tof the bottom ci' thesteeringwpest 147,- :alf'ifiich-` retetes i incide of "theffsteeing comme 1^ 11. IB' f of this construction, it will be seen t at rotation affiche sfeeaingfpest attestata; the vehicle to the right or left Willoperate 'through `the cables-Adrenal @loto 'rotate the idisk 29, to move: the wond iLett orj "QtighiA opposite thempeningffa :im the bach plate L21. 1When the-'steeringwwheels are straightened, the disk 29, will be in its normal position with the Word Stop opposite the opening 23. The cables 40 and 41 are also rovided with branch cables 50 and 51 lea ing over the pulleys 50 and 51 respectively, with their ends attached to the steering column 11, slightly below the steering wheel as indicated by 60. By means of this construction, the driver of the vehicle, may pull either of the cables 50 or 51 to cause the disk 29 to rot-ate, even though there is no turning of the steering wheel.

Within the lamp housing 26, is provided an incandescentelectric bulb which may be of the ordinary kind heretofore commonly used in connection with stop signals. This bulb is so connected with an automatic switch in the usual manner, so V,that itnormally'will be out but will light whenpthe brakes are applied. This form of attachment and construction is old in the art and consequently will not be described here.

The lower part of the casing below the opening 23 may carry any suitable emblem or device such as a vehicle license tag as indicated by 80.

The cables 4() and 41 are led from thepulley out of the casing 2O over the two pul leys 90 and 91.

The operation of my improved device is as follows.

When the vehicle is running freely, with out the application of brakes, the light 70 will not be burning and consequently nothing will be visible through the red glass 27 from the rear of the vehicle. 'When the brakes are ap-plied to slow down the vehicle, the liffht 70 will burn, displaying theword Stop through the red glass at the rear. If the vehicle is turned to the right or the left by rotation of the steering column 47, the disk 29 will be turned to display the word Right or the word Left, dependin upon the direction of the turn. If desire the operator can pull either of the cables 5l or 50 to turn the disk 29 to display the word Right or Left to indicate the contemplated turn.

While I have shown and described certain embodiments of my invention, it is to be understood that it is capable of many modifications. Changes therefore in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims, in which it is my intention to claim all novelty inherent in my invention as broadly as possible in view of the prior art.

What I claim as new and desire to secure by Letters Patent, is:

l. In a device of the character described, a cylindrical casing provided with an opening at the rear, a disk rotatably supported in the casing provided with signal words adapted to be brought into registry with the opening by rotation of the disk, and means for automatically or manually rotating the disk, said means comprising two cables attached to the disk and leading forward with their forward ends attached to arms arranged on the steerin post, said cables also provided with brano es leading upwardly to points within reach of the vehicle operator.

2. A device of the character described, comprising a cylindrical casing having an opening at the rear, an electric lamp sir-- ranged opposite and in front of said o ening, a circular disk rotatably mounte in said casing having its periphery lying between said lamp and said opening, said disk bein provided at its periphery with signal words adapted to be moved, by rotation of said disk, into position between said lamp and said opening, and means for automaticaly rotating said disk, said means com rising two cables attached to the disk and cading forward with their forward ends attached to arms arranged on the steering post. l

3. A device of the character described, comprising a cylindrical casing having an opening at the rear, an electric lamp ar` ranged opposite and in front of said opening, a circular disk rotatably mounted in said casing, having its eriphery lying between said lamp and sai opening, said disk bein provided at its periphery with signal wor s adapted to be moved by rotation of said disk, into position between said lamp and said opening, and means for automati cally or manually rotating said disk, said. means comprising two cables attached to the disk and leading forward with their forward ends attached to arms arranged on the steeringpost, said cables also provided with branches leading upwardly to points within reach of the vehicle operator.

In witness whereof I have hereunto set my hand and seal this 12th day of February,
